Question

Which of the following is important in accumulating and removing sand that result in shifting barrier islands?

Answer 1

Answer:

D. Longshore currents

Explanation:

Longshore currents are characterized as the sediment transport that occurs in the surf zone, due to the oblique incidence of the waves, along the beach. A current develops between the beach and the surf zone parallel to the coast, normally between 0.3 and 1 m / s. It is this process that is responsible for accumulating and removing sand that results in displacement of barrier islands.
